Battery Scientist

Reports To: Director of Battery Technology

Coreshell's metallurgical Silicon anode technology delivers high capacity, fast-charging, and superior safety. Our low-cost liquid-phase nano-coating addresses critical electrode-surface degradation issues and enables batteries with a Silicon-dominant anode that have higher energy density, superior intrinsic thermal safety, and significantly lower cost/kWh compared to current LIBs. Our Si anode material is 50% the cost of graphite and 100% domestically sourced. We strive to transform the global automotive market by enabling low-cost and long-range EVs as a first step towards net-zero sustainability in the near future.

Position: Looking for an experienced Battery Scientist with a strong background in battery materials, systems, and electrochemistry to assist our thin-film development for advanced battery chemistries (Si-anodes, Solid-state/Li-metal).

Core Responsibilities:

• Collaborate closely within Coreshell’s technical team to iteratively improve performance of coating materials. Recommend adjustments to coating compositions and physical/electrochemical properties to mitigate interfacial degradation across various battery chemistries.
• Optimize cell manufacturing processes including slurry mixing, electrode fabrication, and final cell assembly.
• Cell testing: Evaluate device level performance under various operating / environmental conditions. Interpret data to recommend changes in cell design to meet performance targets.
• Work across multiple battery systems (NMC, LFP, Graphite, Silicon, etc.) to ensure proper baseline performance in state-of-the-art as well as next generation battery chemistries.

Required experience:

• Ph.D. or equivalent in Battery-related Chemistry, Materials Science, Engineering or a similarly relevant field. 2 years of commercial experience post-Ph.D. graduation strongly preferred.
• Strong background in fabrication and design of lithium-ion battery systems from basic materials and components (electrode powders, slurries, electrolytes, casings, etc.) to full cell design in a variety of formats (coin cell, pouch & cylindrical).
• The ideal candidate will have a deep understanding of parasitic interfacial reactions between electrode active materials and liquid and solid electrolytes.
• Root cause failure analysis in state-of-the-art and next-generation lithium-ion batteries.
• The ideal candidate will have significant experience in using a computational framework for lifetime prediction and interpreting full cell voltage curves.
• Strong materials-level knowledge of battery electrodes and knowledge of electrochemical characterization techniques such as EIS, CV, GITT, etc.
• Knowledge of industrial standards for battery materials, processing, and testing protocols.
• Substantial experience characterizing materials using standard techniques such as AFM, SEM, TEM, XRD, XPS, FTIR, Raman, etc.
• Creative, self-driven, “out-of-the-box” thinker with a long history of problem solving and an ability to wear many hats. The ideal candidate will have a track record of meeting timely technical milestones as well as achieving commercially-relevant product performance targets.
